Transition concave to convex

[kenhills]

Hi All,

I am working on some knives not to dissimilar to the Gerber mark 2. Gerber makes them with a convex grind the length of the blade. What I want to do is to make the entire blade concave. (hollow grind) That is easy to do on the front of the blade but not on the concave section of it. So if any one has any ideas they would be appreciated. The knife you see below started out concave on the front of the blade and I am willing to make the hollow of the blade convex just cant come up with something that looks right. I keep getting a "bump" at the transition point which is slightly past the point where the blade starts to curve in. Any suggestions?

Thanks, Ken
